'MECHANISM FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 312,378, dated February 17, 1885.

Application filed OctoberBO, 1884. (No model.)

T all whom it may concern:

Be it known that I, J ETHRO E. PENOILLE, of Kendall, in the county of McKean and State of Pennsylvania, have invented certain new and useful improvements in Mechanisms for Converting Motion, of which the following is a full, clear, and exact description.

My improved mechanism is specially applicable to steanrengines; and itconsists in a lever mechanism combined with a piston and crank shaft, for operation as hereinafter described and claimed.

Reference is to be had to the accompanying drawing, forming apart of this specification,

which is a side elevation of the mechanism as applied to an engine.

A is an engine-cylinder, and B is a crankshaft.

ln suitable bearings,a,bei.ween the cylinder and shaft, is fitted a rock-shaft, b,at a greater or less height above the level of the engine, according to the length of the levers used. On this shaft 1) in a vertical plane the lever d is fulcrumed and the lower end of the lever d is jointed to the pitman or connecting-rod e.

To the crank of the shaft B is connected a lever, 9, that extends upward and is connected to lever Z by a jointed link, i, at its upper end. Near the lower end of the lever 0 g is connected a link or rod, Z, that also connects to lever d.

In operation the right line movement of the piston and cross-head is communicated through the connecting-rod 6, link Z, and lever 5 g to the crank. The end of the lever d connected to rod e has a movement equal to the length of movement of the piston, and this movement is multiplied by the lever (Z upon the Frank, so that the crank has a longer movement or a movement greater than would 0 be obtained by a direct connection with the pitman. The link Z, by its connection to the levers d g,assists and regulates the movement. By means of this mechanism the short piston movement is made to operate a crank of much 5 greater length, so that there is an increase of leverage and power.

While these devices are specially applicable to a steamengine,they may be appliedgener ally, for converting rectilinear into rotary motion.

Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1. The mechanism for converting motion, consisting of the levers d 9. connected by the 5 5 links a" and Z, combined with a pitman and crank-shaft,substantially in the manner shown and described.

2. In a mechanism for converting motion, the combination of the rock-shaft b, the lever 60 d, pitman e, and lever 9, being connected by the link Z to the lever d, substantially as described.

3. The combination of the two levers d 9, connected, respectively, to a pitman and a crank-shaft, and connected with the link 2', substantially as described.
